ADJUSTING WHEEL-TRACK FOR TYPE-BEDS OF PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 771,865, dated October11, 1904.

Application filed January 5, 1904. Serial No. 187,761. (No model.)

To all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented new and useful Improvements in AdjustingIVheel Tracks for Type-Beds of Printing-Presses, of which the followingis a specification.

By means of this invention accurate adjustment can be obtained withslight expenditure of time, so that the wheels or track of a typebedwill sustain the latter in the position required. Various devices havebeen used for the adjustment of these wheels; but they require theutmost accuracy in adjusting. Hence a screw or wedge will not answer,because any pressure upward on these wheels tends to spring the type-bedor raise it off its normal bearing. Inasmuch as there is'a series ofthese wheels, it is necessary that the top' surfaces of them should beall exactly the same height and level. The least variation from accuracytends to cause trouble.

This invention is set forth in the following specification and claimsand illustrated in the annexed drawings, in which Figure 1 is a sideelevation of a track embodying this invention. Fig. 2 is a frontelevation of Fig; 1. Fig. 3 is a section along 00 as, Fig. 2. Fig. 4 isa section along y y, Fig.3. Fig. 5 is a section along 2 .2, Fig. 3.

In the drawings are shown tracks comprising wheels 6 Three wheels areusually applied in each track; but the number is not limited. Thin metalshims have been used under the journal bearings to adjust the tracks;but manifestly there are objections thereto. The type-bed is shown atit. While receiving the impression the bed rests on'the wheels '6 of theabove-mentioned tracks.

In addition to the wheel-tracks are shown roller-tracks Z, which carryguides for controlling the action of the type-bed sidewise and supportthe bed when not resting on the wheel-tracks. In other words, thetype-bed always rests on the roller-tracks Z and part of the timethatis, when receiving the impressio non the wheel-tracks also.

The journal-bearings of the wheels 6 are shown at m. These bearings resteach on a pivot-bolt e in casting h. The bolts 0 and e are clamp-boltswhich clamp the journal-bearing in any desired position by compressingthe sides of the casting or support it. The bearings m are each providedwith an opening, a slot, and a recess for the bolts 6, e, and 0respectively. This casting is shown resting on the center cross tie orgirth n of the frame under the impression-cylinder 0. Said girth helpsto hold the frame together and also sustains part of the weight of thetracks Z.

Springs are shown at 0* arranged in the recesses of the bearings andeach having a tendency to lift its respective bearing m, with its wheel0 To adjust the wheels 0 the bolts 6 e e are slackened. The wheel isthen sustained by the pivot-bolt c and the spring a". This spring causesthe bearing m to swing upward about pivot e or tends to raise wheel 6above its normal position. When it is raised, it is simply necessary tomove the type-bed over this wheel. The weight of the type-bedimmediately forces the wheel down into the exact position which thewheel ought to occupy, the wheel thus resting up against a planesurface. In this position the clamp-bolts e, e, and c are all screwed uptight, and lthe wheel is retained in the exact position it ought tooccupy. This adjustment can be made in a minute and is practicallyimmovable. By this adjustment it is easy to adjust any number of wheels,(three or.

more,) so that the'upper surfaces will be exactly parallel and allreceive an even share of the load of the impression, and they will .allturn when the type-bed passes over them. With former adjustment ofwheels it has been practically impossible to get them exactly in line sothey will all turn that is, so they will all receive the same share ofthe load.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A type-bed track comprising a plurality of supporting-wheels for thebed, a pivoted and adjustable bearing for each of the wheels, and aplurality of devices for clamping the bearing in its adjusted position,one of said devices acting as a pivot for the bearing to be adjusted on.

2. A type-bed track comprising a plurality of supporting-wheels for thebed, adjustable bearings for the wheels, and pivot and clamp boltsextending through the bearings and adapted to secure them in theiradjusted positions.

3. A type-bed track comprising a plurality of supporting-wheels for thebed, compressible and pivoted bearings for the wheels, pivotbolts forthe bearing, and clamp-bolts for securing the bearings in their adjustedpositions.

4. A type-bed track comprisinga plurality of supporting-wheels for thebed, an adjustable bearing for each of the wheels, a pivot for each ofthe bearings and means for clamping the bearing in a fixed position whenadjusted.

5. A wheel-track having bearings, a support, a pivot-bolt in the supporton which the bearing can swing or adjust, and clampingbolts for fixingthe bearing.

6. .A wheel-track having bearings, a support, pivot and clamping boltsfor the bearings, and a spring for supporting the bearings.

7 A wheel-track with bearings and a support, a pivot-bolt and spring forthe bearings, and clamping-bolts for fixing the bearings.

8. A wheel-track with bearings and a support, pivot and clamp bolts forthe support, and a spring made to coact with the pivotbolt to raise thewheel when the clamp-bolts are loosened.

9. In combination, atrack formed of aplurality of wheels, a separatebearing for each of the wheels provided with an opening, a slot and arecess, a support for each of the bearings, a bolt extending through thesupport and said opening for pivotally connecting the bearing to thesupport, and clamping-bolts extending through the recess and slot forfixedly securing the bearing to its support when said hearing has beenshifted upon its pivot.

10. In combination, a track formed of aplurality ofvertically-adjustable wheels, a pivoted bearing for said wheels, meansfor fixing the wheels and bearing in position when adjusted, and aspring for swinging the bearings upwardly when released.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

GEORGE P. FENNER.
